Abstract
The invention relates to a double-beam circular-ring-embedded contractible support and a using method for using the double-beam circular-ring-embedded contractible support, and belongs to the technical field of coal mine tunnel supporting and protecting equipment. The double-beam circular-ring-embedded contractible support and the using method for the double-beam circular-ring-embedded contractible support aim to solve the problem that a coal mine tunnel is large in convergence and deformation and a supporting and protecting structure is unstable. The double-beam circular-ring-embedded contractible support mainly comprises a top arch support section, two lateral wall support sections and metal connecting clamping cables. The top arch support section and the two lateral wall support sections are all composed of interior steel rib beams, exterior steel rib beams and embedded circular steel rib rings, and each support section is connected to be an integral support through a clamping cable. The double-beam circular-ring-embedded contractible support is simple in structure, small in steel consumption, low in weight and cost, convenient to transport and install, short in limited project time, strong in project practicability, and capable of effectively controlling stability of tunnel surrounding rocks.
Description
Technical field
The invention belongs to the colliery tunnel support equipment technical field, be specifically related to a kind of colliery tunnel support support and using method thereof, relate in particular to the embedded round collapsible timbering of twin beams and using method thereof.
Background technology
Rich coal resources in China, output is big, and the coal seam mode of occurence varies, and mine laneway purposes and production specifications also have nothing in common with each other, and therefore, roadway support work is very complicated, and support form is varied.In the 80's of 20th century, metallic support develops the principal mode that becomes domestic and international mine laneway supporting rapidly, and is developed to the contractibility metallic support by the rigid metal support.For country rock weakness, broken tunnel, metallic support can support rock (coal) body of weak broken well, and the shape and size in tunnel are met the demands, the contractibility metallic support distortion of suitable for surrounding rock body or coal body to a certain extent simultaneously.
Metallic support is generally made with mining i beam or U shaped steel, the steel consumption of this class support is big, cost is high, weight greatly, very heavy, be not easy to transportation and installation, therefore, need invention a kind of new contractibility metallic support and using method thereof, with stablizing of effective control roadway surrounding rock.
Summary of the invention
The purpose of this invention is to provide the embedded round collapsible timbering of a kind of twin beams and using method thereof, this support not only can effectively solve the stability control difficult problem of coal mine roadway country rock, and support cost is low, easy construction, Technological Economy are feasible.
The technical solution used in the present invention is: the embedded round collapsible timbering of twin beams, and it mainly is made up of crown brace sections, two lateral wall brace sections and metal Connection Card cable; Described crown brace sections and two lateral wall brace sections constitute by interior reinforcing bar beam, outer reinforcing bar beam and embedded reinforcing bar annulus, and each brace sections connects into integral support by metal Connection Card cable.
Construction using method of the present invention is: the embedded round collapsible timbering of twin beams and using method thereof, Tunnel Pressure is at first on the estimation determined the model of metal Connection Card cable, with metal Connection Card cable crown brace sections and two lateral wall brace sections are coupled together then, but this moment is fastening metal Connection Card cable not, so that the section configuration of crown brace sections and two lateral wall brace sections is dwindled as far as possible, being convenient to support props in the tunnel, after support is propped, crown brace sections and two lateral wall brace sections are strutted to roadway surrounding rock, make itself and roadway surrounding rock closely connected, after the support section configuration adheres to specification, fastening metal Connection Card cable is finished the construction of an embedded round collapsible timbering of twin beams, and is last, with vertical cylinder lever connecting rod the embedded round collapsible timbering of adjacent twin beams is coupled together, form supporting integral body.
Operating principle of the present invention is: after the embedded round collapsible timbering construction of twin beams is finished, at first utilize the strong characteristics of embedded round anti-pressure ability, reinforcing bar beam and outer reinforcing bar beam in cooperating, the effect of resisting surrouding rock deformation and tunnel mine pressure jointly; Mine pressure constantly increases when the tunnel, and after reaching the stressed limit of metal Connection Card cable gradually, relative slip will take place with two lateral wall brace sections in the crown brace sections, thereby the contracting that has realized entire bracket is moving, avoid the yield failure of support, also guaranteed the stable of roadway surrounding rock simultaneously.
The invention has the beneficial effects as follows: the embedded round collapsible timbering of twin beams is simple in structure, steel quantity consumption is few, cost is low, easy construction, the duration is short, engineering practicability is strong, and can adapt to the stress development of roadway surrounding rock, effectively controls the stable of roadway surrounding rock.
Description of drawings
Fig. 1 is the embedded round collapsible timbering schematic diagram of twin beams of the present invention.
Marginal data: 1-crown brace sections; 2-lateral wall brace sections; Reinforcing bar beam in the 3-; The outer reinforcing bar beam of 4-; The embedded reinforcing bar annulus of 5-; 6-metal Connection Card cable.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the embedded round collapsible timbering of twin beams of the present invention mainly is made up of crown brace sections 1, two lateral wall brace sections 2 and metal Connection Card cable 6; Described crown brace sections 1 and two lateral wall brace sections 2 constitute by interior reinforcing bar beam 3, outer reinforcing bar beam 4 and embedded reinforcing bar annulus 5, and each brace sections connects into integral support by metal Connection Card cable 6.
During use, Tunnel Pressure is at first on the estimation determined the model of metal Connection Card cable 6, with metal Connection Card cable 6 crown brace sections 1 and two lateral wall brace sections 2 are coupled together then, but this moment is fastening metal Connection Card cable 6 not, so that the section configuration of crown brace sections 1 and two lateral wall brace sections 2 is dwindled as far as possible, being convenient to support props in the tunnel, after support is propped, crown brace sections 1 and two lateral wall brace sections 2 are strutted to roadway surrounding rock, make itself and roadway surrounding rock closely connected, after the support section configuration adheres to specification, fastening metal Connection Card cable 6 is finished the construction of an embedded round collapsible timbering of twin beams, and is last, with vertical cylinder lever connecting rod the embedded round collapsible timbering of adjacent twin beams is coupled together, form supporting integral body.
